Plural Sight is the best recommendation for you to learn Angular 2.

Hi David, I'm going with the official documentation (https://angular.io/docs/ts/latest/quickstart.html) and i'm building a project with it. I found myself remembering more easily new stuff when i've stumbled upon issues and find a way to solve them.

You may probably find usefull to look up angular2 source code from Github from other devs ...
